Retaining and Flood Walls
The engineering manual Retaining and Flood Walls from the U.S. Army Corps of Engineers provides guidance for the safe design and economical...

Modular Evolution
The construction industry typically thinks of modular steel bridges in terms of the World War II vintage Bailey Bridge. The Bailey Bridge was designed to be quickly deployed to replace...

Lightweight Concrete for a Segmental Bridge
Structural lightweight concrete can help increase the stiffness and decrease the mass of a bridge; both are qualities that make the structure more likely to survive an earthquake. Ordinarily,...

Circle Integration
Based on the results of proof-of-concept experiments, we propose that an integrated suite of software tools can support both automation and integration of several components of AEC design...

Functional Analysis of the Envelope Design Process for Integrated Building Design
Building envelope failures account for a great portion of building failures. The number of envelope deficiencies would be reduced if the design process was integrated. Integration would...

Construction Problem Solving in a Cooperative Distributed Agent Environment
This paper outlines the research being undertaken by the authors to determine how experts develop solutions to construction problems in a cooperative distributed agent environment which...

The Context?Oriented Model: An improved Modeling Approach for Representing and Processing Design Standards
Current electronic design evaluators employ one of three primary computational models to represent a design standard: the Condition/Consequent, Object-Oriented and hybrid models. The problems...

An Object-Oriented Approach for Reinforced Concrete Design
The use of the object-oriented programming approach in developing applications for the analysis and design of reinforced concrete members is discussed. Two object oriented programming...

Quality of Map Data in Geographic Information Systems
Local government engineers wanting to take advantage of computer aided design (CAD) and geographic information system (GIS) need to understand the quality and accuracy of digital base...

Intelligent Design and Remediation of Shallow Landfill Burial Systems
The SLEUTH (Shallow Landfill Evaluation Using Transport and Hydrology) prototype decision support system (DSS) has been developed for design and remediation of shallow landfill burial...

Representing Design Cases Based on Methods
This paper discusses an approach to representing design cases using the methods used in solving specific design problems. This differs from the conventional representation of design cases...

Representation of Case Memory for Structural Design
One of the major issues to be addressed in the application of case-based reasoning to structural design is the representation of design projects in case memory. The content of the information...

Advances and Challenges in Case Based Design
The application of the case-based design (CBD) method to preliminary building design provides an opportunity to overcome problems associated with traditional computer-based design methods....

Modeling to Generate Alternatives in Discrete Structural Optimization
Structural design, like other complex decision problems, involves many trade-offs among competing criteria. While mathematical programming models are increasingly realistic, there are...

Multicriteria Optimization in Engineering Design
An engineering design optimization problem can be formulated as a search of the solution space for which the relationships among various groups of attributes are given. The search can...

The Safety Advisor: An Interactive Object-Oriented Program for Assessing the Safeness of Roadway and Roadside Designs
This paper describes an object-oriented software tool for performing safety assessments of roadway designs. Safety assessments are used to estimate the effect of changes in roadway characteristics...

Scaling Up is Hard to Do: Experiences in Preparing a Case-Based Design Aid Prototype for Field Trial
We seek to improve the conceptual design process for complex artifacts such as buildings by offering designers access, through an on-line hypermedia library, to documentation and evaluations...

Precedents in Design: A Computational Model for the Organization of Case Knowledge
A computational model of for the organization of case knowledge of precedent knowledge is developed. The model is composed of distinct chunks of knowledge called design stories. A formalism...

Case-Based Design in the SEED System
We present the requirements for case-based design in a software environment to support the early phases in building design and outline an approach to satisfy them. We briefly discuss implementation...

FEM in a Design Code Environment
The results obtained from the use of finite element based analysis tools have created a new problem for designer: Which numbers do we use to check against Code limits? Most of the commonly...
